I don't think Moto needs a new cylinder head, nor does he need to cut the valves seats, Kid.

Moto, you only need to clean up the support surface for the camshaft bushing. You can do it yourself, but you can also take the cylinder head to a machinist. He can inspect the cylinder head, and do any necessary work. I doubt he would charge very much.

You also need to buy a new camshaft and camshaft bearing. You can get these items from Zongshen America, or Taobao. Zonshen America is notorious for poor customer service. If you wish to get the parts from ZA, I suggest you make repeated telephone calls to them, instead of relying on emails.

You will probably get better prices, and have fewer headaches by ordering the parts from Taobao, using an agent such as TBTrends.
